A physically modeled piano synthesizer plugin using digital waveguide synthesis.

• Physical modeling synthesis based on digital waveguide string models
• Hammer-string interaction simulation
• Longitudinal string modes
• Soundboard resonance
• Available as VST, VST3, AU (macOS), and LV2 (Linux) plugins

• CMake 3.16 or higher
• C++17 compatible compiler
• Platform-specific dependencies:
  • macOS: Xcode
  • Windows: Visual Studio 2019 or higher
  • Linux: GCC/Clang, ALSA, JACK, and X11 development libraries

# Configure
cmake -B build

# Build
cmake --build build --config Release

The built plugins will be in build/Piano_artefacts/Release/.

The project includes a comprehensive test suite with unit tests for internal components and integration tests for audio output.

# Build and run tests
./test.sh

# Run with AddressSanitizer
./test.sh Release ON

# Run in Debug mode
./test.sh Debug

• Unit Tests: Filter, Hammer, MSD2Filter, ResampleFIR, DWGS (Digital Waveguide String) classes
• Integration Tests: Scale test, Chord test, 4-minute stress test
